Seat Belt Warning System- All 1972 Triumph Vehicles

April, 1972

Federal Safety Standard number S208 requires that all passenger cars manufactured on or after January 1, 1972 shall be equipped with a seat belt warning system provided for the front seats.

As in the case of the ignition audible warning system, it is necessary to ensure that all vehicles so equipped are not delivered to retail customers unless the seat belt warning system is fully functional.

This item should be checked at Pre-Delivery, 1,000 Mile Inspection, and all subsequent service intervals.
